Abstract: The developmental zero,effective accumulative temperature(EAT),and fecundity for three species,namely,Aphis craccivora,Acyrthosiphon pisum and Megoura japonica,were studied.The results showed that the developmental zero of A.craccivora,A.pisum and M.japonica were(6.05±1.44)℃,(5.69±1.72)℃,and(4.02±2.22) ℃.The EAT of the three species were(106.63±9.19),(113.01±2.98),and(131.45±29.84)℃ day-degree respectively.The range of fit temperature for three species is 19-23℃.Under 19℃ all of three species can lay more number of nymphae than that at other temperatures and A.pisum has the highest fecundity among the three species,69.5 nymphae on average laid by a female in her whole life.

Key words: Aphis craccivora, Acyrthosiphon pisum, Megoura japonica, Developmental zero, Effective accumulative temperature, Fecundity
